This unprecedented amount of data is characterized by ocean-scale coverage with high spatial and temporal resolutions, but also by different data formats and specifications depending on buoy model and brand, as well as on the type of data exchange agreements into play. Their use for scientific and management purposes is therefore critically dependent on the abilities of algorithms to process heterogeneous data formats and resolutions. This paper proposes a unified set of algorithms for processing the buoys location data used by the two major purse seine fleets operating in the Atlantic and Indian oceans. Three main issues that need to be addressed prior to the exploitation of the data are identified (structural errors, data records on land and on-board vessels) and five specific filtering criteria are proposed to improve the data cleaning process and, hence, quality. Different filtering procedures are also compared, and their advantages and limitations are discussed. specialized Instrumented DFADs satellite-linked buoys purse seiners tropical tunas data processing ATLANTIQUE OCEAN INDIEN 040 126 Aquatic Living Resources 35 13 [10 ] 2022 0990-7440 https://www.documentation.ird.fr/hor/fdi:010086102 10.1051/alr/2022013 0990-7440 [F B010086102] https://www.documentation.ird.fr/hor/fdi:010086102 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2022-11/010086102.pdf IRD - Base Horizon / Pleins textes 2022-11-09 2025-02-24 fdi:010086102 fre
